To all whom it may concern Be it known that I, WALTER L. Sumo, a citizen of the United States, anda resident of Soldier Pond, in the county of Aroostook and State of Maine, have invented a new and Improved Snow-Plow, of which the following is a full, clear, and exact description.

The invention relates to plows for clearing snow from road-ways, and an object of Reference is to be had to the accompanying drawings, constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views and in which Figure l is a side elevation of a snow plow embodying my invention; Fig. 2 is a plan View thereof; Fig. 3 is a rear elevation with parts in section on approximately the line 3-3 Fig. 2, and with other parts removed; Fig. 4 is. a side elevation of the spiral conveyer for elevating the snow, the'housing of the conveyor being in section; Fig. '5 is a'similar fragmentary View taken at right angles to Fig. 4; Fig. 6 is a detail perspective view of one form' of cutter that may advantageously be employed; Fig. 7 is an enlarged detail vertical section of one of the wheels and its appurtenances for raising or lowering the snow removing devices; Fig. 8

is a detail view in front elevation of the 4 The snow removing devices comprise esrear sled with parts in section on the line 8-8 Fig. 1; Fig. 9 is an inverted plan view of the swivel seat which is shiftablc for the operator to readily turn either of the adjusting wheels; Fig. 10 is a perspective view of the spreader or plow proper; and Fig. 11 is a-front elevation of the frame showing the spindles on which the cutters are mounted adjusted to a greater width than indicated in the arrangement illustrated in the other yseirtially a. spreader or plow proper com- :posed in the mam of diverging sides or wings, the spreader traveling at the approximate center of the machine, and the rear ends of the wings serving feedthe snow to cutters, one of which is ad: jacent to each terminal of the wings of the" spreader, the said cutters in turn forming a feed and delivering the snow to a conveyor,

the conveyor advantageously, as in the pres ent instance, being in the form of a spiral or screw elevator arranged vertically.

Any suitable motor, such as an internal combustion engine is mounted on the frame, and driving connections are made with the arbors or shafts of the cutters and with the screw conveyers that elevate the snow.

In constructing a snow plow in accord to deliver and ance with my invention, a suitable frame work is provided which may consist shown of longitudinal'beams 10 suitably braced by cross bars 11 and bolts 12 or other strengthening means, the frame being mounted on front and rear sleds lit-+141 The front sled has its knee l5 )rcferably' connected with cross beams 16 by a ball and socket joint 17 so as to respond to the unevenness of the road and to the movement of the draft animal; The rear sled, as shown best in Fig. 8, has hinged connection to per mit of forward and backward rocking movement, the said hinged connection being conveniently established by providing disk-like hinge members 18 on the knees 19 ofthe sled l4, and similar hinge members 20 de-* pending from a cross beam or bolster 21 secured-to the longitudinal beams 10. Mombcrs 22 may be employed in' conncction with the crossbeam 21, and the support of the ball of the front sled joint may be secured by arms 24. The snow removing members are mounted about centrally of the machine on a vertical frame 25, on which frame and .advantagcously at the outer sides thereof,

the arbors or shafts 26 of the cutters 27 are mounted in suitable bearings 28-29, said bearings being supported ontra-nsverso rods 28 and 29 or their equivalents. The rods 28 and 29' are supported-from the frame members 25 in any suitable manner. The spreader 3O is supportcd centrally of the machinein front of the cutters 27. In the present instance the saidspreader "is suspended at its apex from an eye-bolt 31 which passes through a transverse hanger beam 32 which is connected near its ends to hanger rods 33, the rear ends of which are connected respectively with sleeves S l'formed The-housings or casings 38 surrounding and carrying the 'spiral conveyers 39 are also supported from the shafts 26 being connected thereto by arms 40 near the top, each arm 40 being forked as at 41 or given a semi-circular form as at 41, and bolted as at I 42 to the housing 38. Similarly arms 43 extend rearwardly from the collar 37 and extend in the form of a semi-circular fork 44 which is also bolted to the casing- 38. Said casing is provided at its lower end with a bootor horizontal receiver 45, to and through which the cutters 37 deliver the snow, and at the upper portion the said housing is provided with any suitable chute or outlet.46 through which the snow is discharged toward the side of the road.

In the example shown, the spreader Wings are each provided with a horizontal cutting blade 47 having transverse cutting edge 48 and desirably also with an auxiliary vertical cutting member or blade 49, the cutters 48 being suitably secured to the Wings as for instance by means of the flanges 50 bolted to the inside of each wing 30. Between the spreader wings 30 and connected therewith, toggle arms 5l-are secured at their forward ends to the respective wings 30 and connected to each other at 52; similarly at any desired point below the adjusting devices 51 thereare secured to the inside ofthe wings 30 hinge members 53 united to each other as at 54 The elements 5153 serve as braces. The cutters may be in the form of two or more spiral blades, two being shown in the present instance as in Fig. 6. Ad-

vantageously the actuating" means for the cutters, cutter shafts-and the conveyers may be as. follows: On the shaft 54 of each c0nveyer 39 is a sprocket Wheel 55, and the sprocket chain 56 extends around said wheel and a sprocket wheel 57 on each arbor 96 for driving the spiral conveyor. The arbors are provided with suitable driving connections from any approved form of motor 58. The adjustment of the Wings, to spread or contract the same, is accomplished manually in the illustrated example.

In the illustrated construction, there is a driving shaft 59 mounted in bearin 60 at the top o -"the frame 25, said sha t being actuated frdmthe motor 1) suitable connections such as sprocket w eels 61 -62 and chain 63 and driving connection between the shaft 59 and the arbors 26 is effected by means of beveled pinions 64, 65 on the'said shaft and arbors respectively. The mentioned racks 35 are suitably held one on each arbor 26 as by set collars 66, and meshing with said racks are the spur pinions 67 .on a transverse shaft 68 which is provided also with beveled pinions 69 that mesh with similar pinions 70 on longitudinal shafts 71 the cutters, the spreader 30 and the spiral conveyers 39 with their housings 38. Thus the described snow removing members may be raised and lowered as desired. When it is desired to leave a ridge or comb in the road-way, instead of clearin the snow sub stantially to the road leve, thdspreader arms 36 may be sustained in a more elevated position by adjusting the bolt 31 in the hanger beam 32 and securing the arms 3.6 at the upper series of bolt holes 36.

In order that the drivers seat 77 may readily swivel to enable the driver to turn toward either one of the hand wheels 76, the said seat provided and mounted to conveniently turn on a spindle 78'. The seat support 81. is provided with arcurte slots 79 through which studs 80 project from the scat.

Each hand wheel 7 6 is provided with suitable means for holding it in any given position to maintain the snow cutters, etc, in the adjusted position, I have shown. the wheel provided with a pin 82 movable vertically in a housing 83'and provided with a head or grip 84. A spring 85 normally tends to press the pin into engagement with any one of an annular series of recesses 86 in any suitable portion in the framework below the wheel.

In Fig. 3 it will be seen that the shaft 59 is divided, the ends being coupled by flanges 87 or other suitable means. Similarly, the transverse rods 28 and 29 are divided, and the divided ends secured by flanges 88-89. All the mentioned flanges are bolted together.

In Fig. 11 I have shown thearbors 26 adjusted to a greater distance from the sides of the frame to correspond with a widening of the plow proper or spreader 30. The wider adjustment of the arbors 26 ,ls-etfected in the present instance by interposing a section 90 in the shaft 59 as clearly shown in Fig. 11. Similarly sections 91 and 92 are interposed in the rods 28 and 29. On the runners of both the forward and'the rear sleds, sharpened plates '93 are secured to prevent side movement of the sleds.

Having thusdescribed .my invention, I

claim as new and desire to secure by Let 'the cutters and having diverging Wings leading to the cutters, and elevating conveyer screwsfed by the cutters,'the said conveyer screws having housings provided with 'dischargechutes.
